									?What is a reflection hologram?

A reflection hologram is the one of the many kinds of holograms available in the
market. They can be easily located on a number of our everyday purchases like vests,
bags, reflective labels, sunglasses, compact discs, etc. Reflection holograms are often
confused with the transmission holograms, but actually they are different.

How does a reflection hologram work?

A reflection hologram is a special kind of hologram in which a three dimensional
image is visible when seen from a particular angle. It is only at this particular angle
that a normal hologram is visible as a three dimensional and multicolor hologram. In a
reflection hologram, how the hologram is visible in its three dimensional and
multicolored version is dependent on the angle of light and the angle of the hologram.
To be more precise and correct, it is the angle of the object beam and the reference
beam.

How the hologram is visible in its three dimensional and multicolored version is
dependent on the angle of light and the angle of the hologram. To be more precise and
correct, it is the angle of the object beam and the reference beam. In a reflection
hologram, the image is stored inside an emulsion. This emulsion stored image is
viewable only when white light falls on it. The image is reconstructed only at the
point and time of the interaction of two beams of light, namely object beam and the
reference beam, traveling in opposite directions. If the light falling onto the hologram
is not at the accurate angle required to make the image visible, the hologram, by itself,
selects the beam of light, that is falling on the required angle for it to be seen in
multi-color and three dimension form, and then reconstructs the image. The extra light
passes through the hologram without being reflected.
